Application filled May 12,`

To all whom it may concern K' Be it known that I, JOHN P. GERAGHTY; a ycitizen of the United States, anda resident ofvJersey City; in thecounty of Hudson and State of New Jersey, have'invented a new andimproved Automobile Lock, of which the following is a full, clear, andexactr description.v A

rl`he invention relates to locks for use on automobiles, auto-trucls andother power driven vehicles or crafts using gasolene or other liquidi'uel as the motive agent.

The objectief the invention is to provide a new and improved lock moreespecially designed to prevent feeding of the gasolene to the carbureterand thus prevent an unauthorized person from running the vehicle.

Another object is to securely lock the device tothe vehicle and thusprevent removal of or tampering with the lock by unauthorized persons. y

Another object is to permit of readily attaching the lock to powerdriven vehicles as now constructed and without requiring a materialchange thereof.

- f .With these and other objects in view, the

invention consists of certain novel 'features of construction, ashereinafter shown and .described and then specifically pointed' out inthe claims.

"A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification7 in y.whichsimilar characters ofv referencel indicate corresponding parts in allthe views. Figure 1 is a si e `elevation of the improved lock as appliedto-a Ford automobile',

parts `of which are shown in section;

"Figure 2 is an enlarged front elevation partly in section ot" the valveconnecting the feed pipe with the carbureter;

Figure 3 is an enlarged sectional side elevvation of the improved lockas applied Figure 4 is a'sectional plan view-ot the same on the line 4 4of Figure 3;

f Figure 5 is a similar view of the same on the line 5 5 of Figure 3;and v Figure 6 is a similar view of the saine on the line 6 6 of Figure3. Theoutlet end of the gasolene feed pipe 10 isconnected by a coupling11 (see Figure 3) with a nipple 12 formed on a valve body 13 havin@y anipple 14 connected with the inlet 15 see Figure 2) ot'a carbureter 16of anautomobile or other power driven vehicle, motor boat, .aeroplane orother mathe upper end of the valve body angle between the tube 1920.serial No. 380,765.

pipe 10 and the carbureter 16. The valve`520 1s pressed upward by aspring 21 seated I in of the valve body 13 to hold thev the bottom valve2O in closed position and against a bearing 22 screwed vor otherwisesecured in the upper'end of plainly shown in Figure 3. The valve body 13is inclined upwardly and rearwardly, fas plainly shown in Figures: 1andv 3', and'fon 13'is sethe' valve b'ody 137 as.y

cured a tube 25 extending upwardly'and.;

rearwardly through the footboard 26 of their body of the-automobile. Thetube 25' forms a part vof a housing 27 provided with a verticaleXtensionQS. The housing 27 lis preferably made intwo` (see Fig. 6)one'o ot' the tube 25 and the other havingv the exn tension 28.1 By thisarrangement sections can be readilyl yadjusted vto vary the partsscrewed together, the sectionsbeing part.

the casing e so I 25and the extension 28 according to conditionsfonl'dierent ane-'' tomobiles. In the bearing 22 is mounted to slide thelower portion of or stem 30 is vmounted to slide inthe hous-4 a. bolt orstern 30 engaging. or form-ingy part ot the" upper end/of the Vvalve 20,and the upper portion lof the rod x ing 27 and'is provided with a rack31in mesh with a gear wheel 32 mounted to turn on. a stud'33 attached tothe housing 27. The

-gear wheel 32 isintegral with another gear lwheel 34 thus forming adouble gear, wheel,

and this second gear wheel 34l is in mesh with a rack 35 formed on thelower reduced portion`36 of avertical spindle 37 extending throughk theextension l28 andthrough a nipple 38 screwing into the extension 28.v

The niplple 38 forms an integralpartfof the bottom 39 of a lock casing40 otav permutation l'ock, ofwhich the sliding member. The upper reducedportion 41 of the spindle 37 extends' through a boss 42 integralwith thetop 43 of the Ilock casing 40 and on the upper outer end of the reducedspindle portion is arranged a knob y 10o spindle 37 is a.

44. adapted to be manipulated'by the operator in charge oftheautomobile.

Between the .bottomv 39 and of'the lock casing 40 are arranged aplurality of disk tumblersy 50 having central iio openings 51 throughwhich extends.. the

vopenings with vertically alined lugs 61 adapted topass through the saidnotches 60 at' the time the latter are 4in verticalalinement, as shownin Figure 3. It any one, several or all 1 of the tumblers, however, are

c turned andl theI corresponding notches 60 move out ot engagement withthe corresponding lugs 61 then downward movement ot the spindle 37 isprevented and the valve 2O is held in closed position. Whenv the notches60 are in alinement with the 'lugs 61 then the operator can push thespindle 37 downward to rotate thek gear wheels34, 32 whereby the rod orstem 30 is moved downward and likewisethe valve 20 to thusk move thelatter into` open positionto connect the feed pipe 10 with thecarbureter 16.v The reduced portion 41 ot the spindle 37 is provided`with, a key 62 slidingly engaging a keyway 63 formed, in the boss 42to'V prevent turning of the spindle 37. The downward sliding movement ofthe spindle 37 is limited bythe lowermost lug 61k engaging a recess 64formed'in theupper tace of thebottom 39 of the loolr casing 40.

i Each of the tumblers 1s provided'with a. removable rim 70 providedfonits peripheral face with concentric numerals or other `characters usedfor setting the lock to any desired combination. Each rim 70 is providedat its inner face with one or more integral lugs 71 vadapted to engageany one lof a plurality of notches 72 formed on the peripheral tace ofthe body of the tumbler 50. In practice7 the number of notches y72 onyeach tumbler 50 corresponds to the num-- ber oit' characters on theperipheral face of the corresponding rim 70. VBy the arrangementdescribed, the rims can be readily Ire'set on their tumbler bodies toprovide a` llarge number of different combinations, that is7combinations that can be made bythe operator in charge of theautomobile.

rlhe lock casing 40 is .connected by a hinge with the instrument board81 and by a link 82 with the dashboard 83 of the autof mobile(seeliigures 1 and The hinge 8O is arranged to; prevent an unauthorizedperson trom removing the permutation lock from the automobile and torthis purpose the following construction is made.-

' The back 55 of the casing 40 is provided on its upper endl withyspaced eyes 85 through which extends a pintle 86'eXtending through aneye 87- and screwing in an eye 88, the eyes 87 and 88 being :termed ontheL hinge leaf 89 riveted or otherwise permanently secured to theinstrument boa-rd 81. Between the eyes 85 ofthe back 55 is arranged anapertured block 90 which covers up the head of the casing bolt 54, andthrough this block 90 eX- 'tends' the pintle 86. The latter is providedwithin the block 90 with areduced portion k91 adapted to be engaged by alocking bolt 92 mounted to slide longitudinally in the block 90 andlextending thro-ugh a bearing arranged in a bore 94 formed on the top43.v 'T he inner end of tlie'bolt 92 is provided with a head 95 pressedon by onelend of af' spring 96. heldin the bore 94 and seatedon thebearing 93. The bolt head 95 is adapted to be engaged bythe tree end otaI push farm v tulcruined on a pivot` 101 held onI the' spindle 37. Whenthe spindle 37 moves int'o` uppermost position then the arm 10G-pushesthe bolt 92 forward into engagement rwith n `the reduced portion 91 otthe pintle 90 thus i holding the latter against removal by unau thorizedpersons at the time the valve 20`isi in closed position and the operatorhastemn porarily leitthe automobile. The armi-100 is adapted to foldinto a recess 102 formed in the spindle 37 andv its reduced portion* 41ward. lWhen thespindle 37 is moved downwardby the operator after thetumblers of .whenever the spindle 37 is pushed'downthe permutation lockhave been,` set to the properk combination by the operator then the arm100 releases the bolt 92 andthe latter moves rearward by the actionotits spring 96 to withdraw the bolt 92 from the `pintle86 and thus allowremoval ot the same vbythe operator fory detaching the permutation lock.trom the instrument board 81 anddisassem` bling the permutation lockfor changing the` combination whenever it is desiredtov do so.

It is understood that after the pintle 86 is removed the blockV 90 canberemoved. from the casing top 43 tok enable thle operator to i gainaccess to the headof the .boltf54 for removing the latter toy permitthe` operator y to disassemble the lock casingv for changing thecombination orL for other purposes.` vrBy.

the construction described the parts ofthe permutation lock can bereadily assembledor disassembled and thexloclr can bei-:securelyfastened to the instrument board 'and' with#v out danger ot beingremoved ortampered 1 with by unauthorized persons. The stud 33 besidestorming' va bearing tor the' double gear wheel 32, 34 serves toho-ld1the1coverf1l0 ot' the housing 27 inplace (see Fig. 6).' On thecover is riveted .a pin 111 hav-ing a cutoutrportion 112 fitting theupperportion o'l the rod or stem" 30L to Vhold the c0ve'r1310 againstremovalby kan unauthorizedperson.

Whenthey operator is in charge "of the Yautomobile the spindle 37 isv.pushed downward to cause. the valve 20 to move ntooipen' p-O y `sitionand thus connect; the' feed. pipe l0 with the carbureter 16. The spindle37 can now be locked in this lowermost position by the operator turningany one ofthe tumblers 50 to move the corresponding notch 60 out ofregister with the corresponding lug 6l of the spindle whereby the latteris held against upward movement. During the running of the automobilethe operator need not pay any attention to the lock. When the automobileis stopped and the operator intends to leave the car then it isnecessary for the operator to set the tumblers 50 to the desiredcombination to allow return or upward movement of the spindle 37 with aview to move the valve 20 into closedposition. The operato-r next turnsone or more tumblers to locking position to lock the spindle 37 inuppermost position and thereby prevent an unauthorized person fromstarting the engine and running off with the automobile owing to lack offuel.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:-
